functionality was demonstrated. It was found that the reaction of [5-(1,1,2,2-tetrafluoroethoxy)-4-phenylthiazol-2-yl]amine with acyl and sulfonyl chlorides leads to products resulting from substitution exclusively at the exocyclic nitrogen atom. The halogen atom at position 2 of thiazole ring is substituted by S-nucleophiles or hydrogen atom upon catalytic hydrogenation on Pd/C. 2-Bromo-5-(1,1,2,2-t
在本研究中,变换的可能性[5-(1,1,2,2-四氟乙氧基)-4-苯基噻唑-2-基]胺向2 - halothiazoles和偶氮化合物通过证明了胺官能团的重氮化。已发现[5-(1,1,2,2-四氟乙氧基)-4-苯基噻唑-2-基]胺与酰基氯和磺酰氯的反应产生仅由环外氮原子取代产生的产物。在Pd / C上催化氢化时,噻唑环第2位的卤原子被S-亲核试剂或氢原子取代。2-溴-5-(1,1,2,2-四氟乙氧基)-4-苯基噻唑已成功用于通过转化为有机镁中间体的方法合成相应的α-噻唑基苄醇和2-甲酰基噻唑。证明了在上述转化中四氟乙氧基的稳定性。
